Sorry if I made it more difficult than it had to be. The list does not need to be ranked. This works because the NSFC listed their films in alphabetical order. As for the 100 that they didn't have, that is on the money. Interesting list by the way, a few sure shots, and a couple of surprises. Just to let you know, Nights of Cabiria made their list, grouped with La Strada. Close enough, and feel free to substitute.
